Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning windshield tools, in particular to an air-conditioning windshield with an air purification function. Background Art

[0002] Airborne transmission is a key vector for the spread of bacteria and viruses. Currently, the main method for sterilizing and disinfecting the air is spraying alcohol or disinfectant. However, since alcohol cannot be sprayed throughout the entire space, there are also issues such as volatilization, untimely spraying, and explosions when exposed to open flames, resulting in poor sterilization and disinfection effectiveness and high safety risks.

[0003] Air conditioners are appliances used indoors to lower or raise the indoor temperature. They can sterilize and disinfect gases by installing lamp beads and photocatalysts at the air outlet. A search revealed a patent application with publication number CN117346336A, titled "An air conditioner windshield with sterilization and disinfection functions." The patent discloses an air conditioner windshield equipped with lamp beads and photocatalysts. The patent's shortcomings are that the photocatalysts are located on the surface of the ventilation space where the lamp beads are located. The patent's implementation is limited, and it blocks part of the air outlet, preventing air from flowing through the photocatalyst surface. This reduces the contact area between the air and the photocatalyst, preventing the catalytic effect from being fully realized. Furthermore, the patent lacks any preventive measures against ultraviolet lamps, so there is a risk of exposure to ultraviolet rays and this patent is not suitable for home use.

DETAILED DESCRIPTION

[0027] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.

[0028] like Figures 1-6The air conditioner windshield with air purification function shown in the figure is installed on the air conditioner indoor unit and opposite to the air outlet of the air conditioner. The windshield includes an outer shell 1, an intermediate frame 2 and an inner shell 3 arranged in sequence from the outside to the inside. Specifically, the intermediate frame 2 can be connected to the outer shell 1 and the inner shell 3 by a snap-fitting manner. A through hole 30 is opened on the inner shell 3. An inner lamp bead 4 is installed in the through hole 30 through a mounting bracket. The inner lamp bead 4 is an ultraviolet lamp bead. A photocatalyst plate 5 is provided on the intermediate frame 2. The inner lamp bead 4 is opposite to the photocatalyst plate 5. An outer lamp bead 13 is installed on the side of the outer shell 1 opposite to the intermediate frame 2. The outer lamp bead 13 is opposite to the photocatalyst plate 5. A plurality of air holes 10 are opened on the outer shell 1. It should be noted that the photocatalyst plate 5 is a structure in which a photocatalyst is coated on a substrate with holes in the prior art. The substrate can be made of a porous ceramic filter element or other plate material. The provision of the through hole 30 allows the inner lamp bead 4 to have an irradiation distance from the photocatalyst plate 5.

[0029] It should be noted that the power supply wires for the outer lamp beads 13 and the inner lamp beads 4 are connected to the sockets on the wall;

[0030] A first filter layer 6 is detachably mounted on a side of the inner shell 3 away from the middle frame 2. The first filter layer 6 is used for preliminary filtration of the gas discharged from the air-conditioning outlet. In some embodiments, the first filter layer 6 is preferably an activated carbon mesh, and the through hole 30 is provided to ensure that the gas discharged from the air-conditioning outlet can quickly and smoothly enter the photocatalyst plate 5.

When the gas passes through the photocatalyst plate 5, the ultraviolet rays emitted by the inner lamp beads 4 and the outer lamp beads 13 and the catalytic action of the photocatalyst degrade the formaldehyde, benzene, TVOC, etc. in the gas into non-toxic and harmless water molecules and carbon dioxide. In addition, the ultraviolet rays themselves have bactericidal and disinfecting effects, thereby achieving the effect of air purification.

The connecting portion 9 has a first connecting rod 90, a second connecting rod 91 and a third connecting rod 92. The second connecting rod 91 and the third connecting rod 92 are both connected to the first connecting rod 90 to form a herringbone structure. The first connecting rod 90 is connected to the clamping portion 11, the second connecting rod 91 is connected to the upper part of the outer shell 1 or the inner shell 3 or the middle frame 2, and the third connecting rod 92 is connected to the lower part of the outer shell 1 or the inner shell 3 or the middle frame 2.

The upper contact rod 110 and the lower reinforcing rod 111 are both arranged between the first side clamping portion 112 portion 11 and the second side clamping portion 113 portion 11 and are parallel to each other. The upper contact rod 110 is in contact with the top of the air-conditioning indoor unit, and the lower reinforcing rod 111 is in contact with the bottom of the air-conditioning indoor unit. The first side clamping portion 112 and the second side clamping portion 113 are parallel to each other and are located on opposite sides of the air-conditioning indoor unit, and the lengths of the first side clamping portion 112 and the second side clamping portion 113 are adjustable.

[0038] The first side clamp 112 and the second side clamp 113 both include an upper fixed rod and a lower adjustment rod, the upper fixed rod is fixed on the upper contact rod 110, the lower adjustment rod is vertically rotatably installed on the lower reinforcing rod 111, and the lower adjustment rod is connected to the upper contact rod 110 by a threaded manner, and the total length of the first side clamp 112 or the second side clamp 113 is adjusted by rotating the lower adjustment rod.
